The Importance of Grain Boundary Character Distribution to Grain Boundary Design
Published online by Cambridge University Press: 26 February 2011
Abstract
The importance of grain boundary character distribution (GBCD) for the grain boundary design of polycrystalline materials with desirable properties is discussed. The GBCD which describes the type and the frequency of grain boundaries is regarded as the most important microstructural parameter controlling the bulk properties of polycrystals. This parameter can link the bulk properties with intrinsic or extrinsic properties of individual grain boundaries. The recent experimental work on GBCDs in metallic and ceramic polycrystalline materials is discussed. Particularly the relationship between texture and GBCD is discussed in detail in the light of recent studies on several polycrystalline materials with different types of texture. It is pointed out that we are now in a position to quantitatively design and precisely control GBCD in order to endow polycrystalline material with desirable or new properties.
